Webinar series: interference hunting

Watch our experts in four modules and upskill your interference hunting

Unwanted transmitters are pervasive in today’s mobile networks, degrading network capacity and reducing subscriber QoE. With the densification of cells and the deployment of emerging standards with higher-order modulation over legacy technologies, the RF environment is becoming ever-more complex making networks increasingly susceptible to interference. Therefore, hunting down interference is getting more important, if not a must, for many network operators and regulators to protect their investments and keep their network performance to the maximum.

Join our experts for an on-demand online training program packed with a series of four webinars for you to upskill your interference hunting.

What will you learn:

Recognizing and identifying interference
Locating interferers
Practical examples and case studies modules
R&S interfernece hunting solutions

Who is it for:

Interference hunting professionals of

Regulators
Mobile network operators
Service providers

Webinar modules

Module 1: Recognizing and identifying interference

In this webinar, we will discuss how to recognize the presence of interference and how to obtain useful information about the interferer before and during the interference hunting process:

What is interference?
Recognizing interference
Categorizing interference based on spectral characteristics
Harmonics and intermodulation
The role of demodulation

Module 2: Locating interferers

In this webinar, we will discuss the tools and techniques needed to physically locate sources of interference:

Different phases of radiolocation (general vs. local area)
Direction finding tools
Understanding propagation
Using visual clues and other resources

Module 3: Practical examples and case studies

In this webinar, Paul will use actual field cases of interference hunting to illustrate the concepts and techniques presented in the previous presentation

Example 1 : Cable television signal egress
Example 2 : Illegal cell phone repeaters
Example 3 : Pirate radio station
Example 4 : Cellular and other jammers
